EDME THEODORE BRENOT, OF PARIS, FRANCE.

CAUTERIZING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 255,582, dated March 28, 182.

l Application filed March 1, 1882, (No model.) Patented in France February l0, 1831.

To all whom it may concern Beit known that I, EDME THEoDoRn Een NOT, of Paris, in the Republic of France, have invented a certain new and useful Improvement in Canterizing Apparatus or Thermo-f Uanters, of which thc following spceiticatiou is a full description.

This invention relates to cauterizing apparatus in which a suitable eanterizing-iron or hollow metallic tip is' heated to theI temperature required for ca uterization by means ofthe combustion within itself of carbureted air or similar t'uel, and has for its object mainly to furnish a supply of pure air to the said fuel, and to enable the combustion or llame within the tip to be regulated at will by the operator. The air-supply is furnished by a tube separate from that whereby the carhureted air or similar fuel is conveyed,.but connected with the same bulb or air-forcing device, so that one movement forces air through both.- The two tubes are preferably placed concentric, one inside ofthe other, so that externallythere appears but one tube. The regulation ofthe combustion or llame is effectedby a valve placed in the handle which carries the tip, and capable of being readily controlled bythe operator.

The accompanying drawings, which form a part of this specification, represent ,a cauterizing `apparatus constructed in accordance with theinvention.

Figure l is a view in elevation of such apparatus with a portion ot' the canterizing-iron or tip removed, but otherwise complete; Fig. 2, a view in section of the carbureting-vessel and portions of the connected tubes; Fig. 3, a section ofthe handle and valve apparatus, and Fig. 4 an elevation ot' the cauterizing-iron or tip and a portion of the handle.

A is an elastic ball with valves, serving to force the air into the regulating-chamber B, and thence through the tube G, carburetor E, tubes H G, and hollow handle I to the canterizingiron or tip K. The parts A, B, C, E, and K are or may be of any ordinary or suitable construction. The tubes C G H are connected with the three-branched hollow connectionpiece D. The tube C lits over the nipple a,

i the tube G over the nipple b, and the tube H over the nipple g. The tube H is of smaller diameter than thevtube G, and is inclosedk by it, so that an annular space is lett between itselt' and the inner wall ofthe tube G. Acontinuous passage, c, extends through the two lateral branches ot' the connection piece D and puts tube H in free communication with tube (l. The depending; branch, which is inclosed by the stopper ofthe vessel E, is pierced with au inlet'passage, d, connecting the horizontal passage c with the interior o't' the said vessel, and an outlet-passage, c, connectingr the interior ot' vessel E through the lateral passage e with the tube G. The air forced through the tube C by the bulb A passes partly into the vessel E, where it becomes carbureted by the hydrocarbon liquid therein contained, and whence it passes into the tube G and partly into the tube H direct. The opening e' at the bottom of the depending branch is made small, and an additional orifice, c', is made a short distance above, so that by sliding the connection-piece D iu the stopper of vessel E the said lateral ori tice may be covered or uncovered and the flow of carbureted air correspondingly diminished or increased.

Thetubes G H are connected with thehandle l, the tuoe G communicating through the oritices s at the rear or lower end of the handle. A valve, h, regulates the proportionate quantities of carbureted air from the tubeG and pure. air from the tube H, which pass through the tube l into the cauterizing-iron or tip K, wherein they are ignited. The valve h is attached to a rod, r, sliding in a cross-bar, t, and attached at the opposite end to the disk 7c, which is itself connected by means ot' the rods m with a sleeve, n, surrounding the tube Z and engaging by an external screw-thread with the thumb-nut O. By turning the nut O in one direction or the other the valve h is raised or lowered across the orifices s, so as to admit into the tube l less or more carbureted air from the tube G. The composition of the gaseous mixture admitted into the tube Lis thus controlled, and the combustion within the tip or cauterizing-ironKconsequentlyregulated. In-

lasmuoh as the ilow of pure air is checked at the same time that the flow of carbureted air is increased, the apparatus is very sensitive.

A light spring, j, 1s interposed between the cross-bar t and a collar on the rod r, to facilitate the operation ot' the valve. The amount ot' regulation effected by the valve h being limited, any' inconvenience which might arise from excess otl vapor being given oit" by the caibureting-liquid in the vessel E is remedied by sliding the connection in the stopper so as to cover the oritice ef.

The part N is connected loosely with the handle, so as to turn freely thereon. It is notched, as shown at N', to receive an arm, P, fastened to the outer casing ot' the tip or cauterizing-iron, so that by turning the said part N the tip or cauterizing-ixon can be unscrewed or the vents be opened or closed without the operatois burning hisngers.

Moditications may be made in the details ot' construction without departing from the spirit of the invention, and parts of the invention can be used wit hout the others. Thus, in place ot' the thumb-nut 0 for regulating the valve h, other equivalent sliding or turning devices could be used.

Having now fully described my said invention and the manner in which the same is or may be carried into eii'ect,what I claim isl. r1`he combination,with the hollow7 tubular handle ofthe cauteriZing-iron, of means, as indicated, for controlling the supply ot' t'uel, adapted to be Operated by the hand which grasps said handle by means ot' a thumb-nut or its tquivalent, substantially as described.

2. The combination, with the cauterizing- Y iron and its handle, of the two tubes for conveying air and carbureted air or other suitable ,fuel to the handle, wherein they mix, substantially as described.

3. The combination, with the carburetingvessel and stopper, of the connection-piece-v having inlet and outlet passages and two or more openings into the outlet-passage, and adapted to be moved in and out, so as to cover or uncover one or more ot' said openings, and thus regulate the fiow ot' the carbureied air, substantially as described.

4. The combination of the air-forcing bulb, the carburetor, the hollow handle, the tube leading from the air-forcing bulb to the carburetor, the two tubes leading from the latter to the hollow handle, and the valve apparatus connected with said handle, substantially as described.

' 5. The combination, with the cauterizingiron, its sheath and handle, of a Inova-ble piece adapted to engage the said iron and its sheath, so that they can be 'turnedwithout burning the operatois fingers, substantially as described.

(i. The combination, with the handle and its valve apparatus, of the carburetor, the moval ble connection-piece, with inlet and outlet passages, and two or more openings into the out' let-passage, and the two tubes connecting the handle with said connection-piece, substantially as described.

7. The combination, with the handle and its valve apparatus, of the two concentric tubes, one inside the other, for conveying air and carbureted air or other gaseous fuel into said handle, substantially as described.

In testimony whereot'l have hereunto signed this specilication in presence oftwo subscribing witnesses.
